Well the math you would do is 3346/7. That equals 478. As a fraction in simplest form you could write 478/1
I drew these, as I just did these in math not too long ago. When I shaded it, it was in all four quadrants.
14.4, 120% of 12 is 100+20, 12+2.4 is 14.4
It depends on what its asking for and what dimension it is. If its 2D, the area is lengthXwidth, and perimeter you would add all the side lengths. If its 3D, volume is lengthXwidthXheigth.
14.50 x 2 (2 1/2 hours = 1 hour) = $29.00 + $14.50 (for another 1/2 an hour) = $43.50. Then, divide 14.50 in half for the other 15 minutes that weren't accounted for yet, so: $14.50/2 = $7.25 then add it to our previous total: $43.50 + $7.25 = $50.75 is your answer :) Hope I helped
